Hi, what is the workflow to extract a normal vector from a family instance? familyinstance.facingorientation seems to only extract a 2D vector in the XY plane, at least in my testing. Just not sure how to get started. Thanks!

Woohoo, that’s it: [image] Thank you so much for your help-- I’ve been banging my head against this particular rock for awhile now.

Sorry - labeled that one wrong! It’s in Archi-Lab.

Graph attached.
